PREAMBLE DETECTION DEVICE, PREAMBLE DETECTION METHOD, AND COMPUTER PROGRAM |
摘要 |
<p>The present invention deters a false detection of a preamble by a preamble detection device that detects incoming preamble sequences that are transmitted by means of physical random access channels. This preamble detection device is equipped with: a first threshold value calculation means (203) that calculates a first threshold value from average interference power; a second threshold value calculation means (205) that obtains values representing respective cross-correlations between all preamble sequences that are possibly transmitted and a received signal and calculates a second threshold value from the cross-correlation values; a comparison means (208) that compares the first threshold value with the second threshold value and selects the greater threshold value as a detection threshold value; and a detection means (209) that detects a preamble sequence having a cross-correlation value larger than the detection threshold value as a received preamble sequence.</p> |
